Perception is Reality

Perception is reality in this first person puzzler developed by Pillow Castle Games.Museum of Simulation Technology, which is currently the working title of the game, is inspired by “forced perspective”, a camera trick, which makes things appear smaller or larger, depending on where the viewer is standing. In the game, this translates to being able to grab objects of any size and move them around, forcing them to grow multiple stories high, or shrink to the size of a tiny pixel.

“You can grab an object and when you put it down, it will adapt in size and distance
according to your perspective.”

There are other ideas in the game that compliment this mechanic, for example, some objects don’t just scale in size but in property as well. If you take a look at the video below, you see that when the player makes the fan grow larger it will also make it stronger, letting it push more air. (@ 3.40)
The game is still in early development; in the FAQ it’s stated that there is at least two more years until release, since they currently have only one full-time developer and making a game is a slow process. In any case, I think you should still keep an eye on it, especially, if you enjoyed Portal. In the meantime, you might want to take a look at their website and YouTube channel, so you don’t miss any important updates.
